Portland

This month, voters will decide whether to approve a plan to fluoridate Portland's water. Supporters say Portland children - especially in low-income families - suffer aggravated dental problems because the city has chosen not to add fluoride. Opponents say water fluoridation is the wrong way to address a public health problem. And so a battle that has played out before at the state level is now going on in Portland. From Oregon Public Broadcasting, April Baer reports.

Portland city employee Reaz Qadir Khan was arrested Tuesday on charges of conspiring to provide "material support" to terrorists. As Kristian Foden-Vencil reports, the US Department of Justice alleges he helped a terrorist plan a deadly suicide attack in Lahore, Pakistan in 2009.

The EPA announced it will redo parts of a study exploring ways to clean-up the Portland Harbor Superfund site. An initial draft prepared by groups that will pay for the cleanup was biased, the agency says. Amelia Templeton of EarthFix explains.

Two people, plus the suspected shooter, are dead after police say a gunman opened fire at a crowded shopping mall in suburban Portland Tuesday. An ambulance took one survivor of the attack to OHSU Medical Center in Portland. The young woman is expected to survive. Correspondent Chris Lehman reports.

Six hours of last-ditch negotiations have yielded a tentative agreement for the Port of Portland and a Longshore union that represents security guards at some marine terminals. This averts a strike that was scheduled to bring work to a halt Sunday.

Wednesday the Portland City Council is expected to pass an ordinance to add fluoride to the municipal water system. Anti-fluoridation groups have been outspoken in their opposition to the move but Mayor Sam Adams and two commissioners have already voiced their support, ensuring a majority on the five-member panel.

Kimberly Kaminski is Director of "Clean Water Portland." Her group opposes adding fluoride to city water supplies.
